Re: Why valgrind tool massif does not print xtree callstack? (arm)

Which version of valgrind are you using ?
You much better should use the last released version (or a more recent GIT version).

Have you compiled your application with -g ?

In case you debug your native executable with gdb and put a break on malloc,
is gdb backtrace command giving a good stack trace ?

If you then debug using  gdb+vgdb your executable running under valgrind,
is then the gdb backtrace correct ?
And when positioned on the break point, what is the output of
   (gdb) monitor v.info scheduler

Thanks
